Follow BODMAS rule to solve this question, as per the order given below, Step-1- Parts of an equation enclosed in 'Brackets' must be solved first, and in the bracket, Step-2- Any mathematical 'Of' or 'Exponent' must be solved next, Step-3- Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated, Step-4- Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated. Given expression is, (840.4 ÷ 7.27 + 2.73) × 50 = ? + 236.5 Applying BODMAS Rule; ⇒ (120 + 2.73) × 50 = ? + 236.5 ⇒ 122.73 × 50 = ? + 236.5 ⇒ 6136.5 = ? + 236.5 ∴ ? = 5900
